Green hydrogen is becoming an important transformation tool with regard to the world’s quest to acquire clean, renewable power. Green hydrogen produces no carbon emissions since it is produced by electrolysis using electricity obtained through renewable sources such as wind or solar energy. This is unlike the grey or blue hydrogen, which is not a sustainable replacement since it requires fossil fuels. It has great potential to decarbonise those industries that are difficult to electrify, including heavy industry, aviation, and shipping. It is versatile and can be utilized as a fuel, energy carrier, or as raw material in the generation of chemicals. Green hydrogen has the advantage of being storable and transportable to long distances, allowing the transfer of energy across the globe and security. It provides a support source of energy that can eliminate the unpredictability of the wind and sun sources. Such nations as Germany, Japan, India, and Australia have introduced national plans to expand hydrogen infrastructure. Green hydrogen can be produced more reasonably and in a large scale due to rising improvements in electrolyser technologies. Green hydrogen may also be used to make green ammonia, a carbon-free source of fuel and fertilizer.
Companies like automobile firms are also investing in alternative ways of charging vehicles through battery electric vehicles but they are going to be using hydrogen fuel cell cars.
It also provides faster refuelling and higher driving distance on commercial vehicles and heavy-duty trucks. Natural gas is being tested in pipelines by blending with hydrogen in an effort to cut the carbon intensity. It allows decarbonisation without having to upgrade the current gas infrastructure fully. In spite of this problem (high cost of production and lack of infrastructure), international investment is expanding at a fast rate. Governments with individual players are making partnerships to boost up green hydrogen ecosystems. It lies on the path to the net-zero goals in 2050 and climate change. The International Energy Agency refers to green hydrogen as a missing link in the diffusion of clean energy. As renewable prices continue to decrease and the climate concern is on the rise, green hydrogen arrived in its time.
It is not just a fuel, it is the fuel of the future, driving a sustainable and resilient world.
